* ''WesternAnimation/AdventureTime'': [[https://www.youtube.com/watch?v=LgZhA2bIfgA This live-action promo for the show]] depicts Mannish Man the Minotaur fighting on the side of the villains, despite not having done anything villainous up to that point.* In ''WesternAnimation/AlvinAndTheChipmunksMeetFrankenstein'', [[{{Literature/Frankenstein}} Victor Frankenstein]] is portrayed as a {{Jerkass}} who threatens to eat park visitors and a CardCarryingVillain who tries to forcibly change Alvin into a monster when he is disappointed by the original monster's gentle nature. In the novel, Victor's characterization is more nuanced, he doesn't actively harm anyone in creating his monster, and he isn't a cackling villain.* From ''WesternAnimation/AroundTheWorldInEightyDays'' we have Fix. Where in [[Literature/AroundTheWorldInEightyDays the original novel]] Fix was a Scotland Yard detective who chased Phileas Fogg because he believed him guilty of bank robbery, here he's a thug hired by the malicious Lord Maze to stop Fogg from [[TitleDrop going around the world in 80 days]] so Fogg could marry Lord Maze's niece.* ''WesternAnimation/TheAvengersEarthsMightiestHeroes'': ** ComicBook/WonderMan was a villain for only one issue of the original ''[[ComicBook/TheAvengers Avengers]]'' series, and has been depicted as a hero for the vast majority of his published existence. Despite this, he's a TragicVillain and member of the [[LegionOfDoom Masters of Evil]] in the show. He does however make a HeelFaceTurn in his final appearance, where he [[spoiler:pulls a HeroicSacrifice to stop Enchantress]].** ComicBook/TheFalcon and Doc Samson appear as part of Code Red, a team of government-sponsored superheroes who act in opposition to the Avengers. In the comics, the Falcon is ComicBook/CaptainAmerica's partner and a longtime member of the Avengers himself, while Doc Samson is an ally of the Hulk. Partially justified though, since it turns out they were [[BrainwashedAndCrazy brainwashed]] by the ComicBook/RedSkull. (And both of them ''have'' had notable BrainwashedAndCrazy stories in the comics; in Falcon's case at the hands of the Skull.)* ''WesternAnimation/TheBatman'':** In the comics, Kirk Langstrom created the serum that turned him into Man-Bat to cure his own deafness, but on ''The Batman'', he transforms himself into the Man-Bat out of a desire to be feared. That said, by his appearance in the fifth season, he's done a HeelFaceTurn, saying that he's done with being Man-Bat and even offers to assist in stopping the Terrible Trio.** The Penguin in more in-line with his ''Film/BatmanReturns'' self and hence is AxCrazy instead of the OnlySaneMan of Batman RoguesGallery.** Unlike in ''Batman: TAS'' where he is a sympathetic figure trying to cure his wife, Mr. Freeze is a thug who enjoy robbing banks.** Chief Angel Rojas is a [[RaceLift Hispanic]] {{expy}} of Harvey Bullock--expect even as a DirtyCop, Bullock had lows he wouldn't sink to, like using fellow cops as a hostage or be a (complete) jackass to other officers, whereas Rojas has done these things.* ''WesternAnimation/BatmanTheBraveAndTheBold'' depicts UsefulNotes/{{the Silver Age|OfComicBooks}} ComicBook/{{Batwoman}} as a washed-up former superhero who captures Batman and then tries to murder the Riddler as payback for ruining her career. The depiction was so at odds with her comic counterpart that the creators were forced to refer to the character as "Bat-Lady" and [[AdaptationNameChange change her name from Kathy Kane to Katrina Moldoff]]. * ''WesternAnimation/BewareTheBatman'':** One example is the BigBad ComicBook/{{Anarky}}. In the comics, Anarky was depicted as twelve year old Lonnie Machin, a political anti-government activist and altruist who saw humanity as naturally good, but with consumerism and big government getting in the way. He wasn't a villain more than he was an anti-hero who even Batman acknowledged was well intentioned but misguided. Beware's Anarky is a self-diagnosed sociopath and aimless terrorist whose only difference between him and The Joker is name and chess theme.** [[spoiler:Sapphire Stagg, the good-natured love interest of Metamorpho in the comics, who is here depicted as very much similar in nature to her corrupt father, Simon Stagg, though her feelings for Metamorpho remain intact.]]** Harvey Dent, who is usually a man of justice and a big supporter of Batman (at least before [[FaceHeelTurn his transformation into Two-Face]]), is now an opportunistic, corrupt politician who targets Batman and Katana as part of Gotham's problem, who eventually teams up with Anarky to kill him and hires Deathstroke to take down Batman.** Sort of with Ra's Al Ghul. His actual motivations are unclear, but he doesn't seem to have the WellIntentionedExtremist goals of his comic counterpart. On the other hand, he seems hellbent on focusing on Gotham only, so the rest of the world doesn't have to deal with genocidal plots.** And then there's Humpty Dumpty. His comic counterpart was a HarmlessVillain at best and a TragicVillain at worst. While he starts off as tragic as his comic counterpart, he's become a sadistic psychopath driven by revenge who loves to put those he feels have wronged him in elaborate deathtraps. Essentially just add [[Franchise/{{Saw}} Jigsaw]] and the Riddler and you've got him.* ''WesternAnimation/CaptainNTheGameMaster'':** Alcuard is a mole and ends up turning on the main characters, including Simon Belmont, in favor of his father, Dracula. In the ''Franchise/{{Castlevania}}'' video games, Alcuard's firmly on the side of the good guys, hates Dracula, and is one of Simon's main allies in the series. ** Also, King Hippo is a thug who works for [[BigBad Mother Brain]] in the cartoon, where he's an AntiVillain at best in ''VideoGame/PunchOut'', hardly as mean as Mac's other opponents. He even offers to take Mac out to lunch!* In the ''WesternAnimation/ColorClassics'' short "Greedy Humpty Dumpty", the title character goes from being a neutral figure to a greedy tyrant who orders his servants and subjects to build his castle walls high enough to reach the sun, which he has become convinced is made of gold.* In the book ''Cranberry Christmas'', Cyrus Grape is a [[GrumpyOldMan curmudgeonly old man]] who refuses to let anyone skate on his pond, but gets his comeuppance when Mr. Whiskers finds a deed that proves the lake is actually on his property. In the animated special, Cyrus is a much more active antagonist, sneaking around and messing up Mr. Whiskers's house in order to keep Mr. Whiskers from finding that deed (whereas in the book he had no idea it existed).* Morrigan in the ''WesternAnimation/{{Darkstalkers}}'' cartoon. In the games, she is just having fun with no regard for the rest of the cast, in the show, she's Pyron's minion. The series finale implies she becomes closer to how she is in the games if a season 2 ever came. Also, Anakaris, Bishamon, and to some extent Demitri were victims of this.* ''Franchise/DCAnimatedUniverse''** ''WesternAnimation/BatmanTheAnimatedSeries'':*** ComicBook/KlarionTheWitchBoy, whose portrayal in the comics generally ranges from an annoying troublemaker (Creator/JackKirby's version) to a well-meaning anti-hero (Creator/GrantMorrison's version), is clearly evil when he appears in ''WesternAnimation/BatmanTheAnimatedSeries'', stealing control of Etrigan from Jason Blood, tearing Gotham apart simply for fun, and using potential lethal spells on Batman when the hero tries to stop him. He finally removes any doubt what a despicable brat he is by telling Etrigan to kill Blood (who is aging at an accelerated rate and nearly helpless due to the Demon being separated from him).*** The tie-in film ''WesternAnimation/BatmanMysteryOfTheBatwoman'' presents Batwoman as a reckless vigilante who doesn't have qualms about lethal force, which is why DC insisted that they didn't use Kathy Kane. This didn't stop the makers from homaging her via naming one of the suspects "Kathy Duquesne". [[spoiler: Nor making that Kathy [[CollectiveIdentity one of the Batwomen]].]]** ''WesternAnimation/JusticeLeague'' and ''Justice League Unlimited'':*** While she didn't know all the details and did a HeelFaceTurn to help her teammates when she realized [[EarthShatteringKaboom what would happen to Earth]], Hawkgirl was still TheMole, spying on the League for Thanagar and helping them occupy Earth in the Season 2 finale.*** This trope is the reason why Aresia, Tsukuri, Hro Talak, Galatea, and the Ultimen are {{Exp|y}}ies as DC wouldn't allow either woman who's been codenamed [[ComicBook/InfinityInc Fury]] to attempt to commit {{Gendercide}} (Aresia), ComicBook/{{Katana}} to be party to said Gendercide (Tsukuri), ComicBook/{{Hawkman}} to be willing to blow up the Earth to help Thanagar win a war (Hro Talak), ComicBook/PowerGirl to be a hitwoman for ComicBook/AmandaWaller (Galatea), or the {{Canon Foreigner}}s and {{Canon Immigrant}}s of the WesternAnimation/SuperFriends (namely Samurai, Black Vulcan, and the ComicBook/WonderTwins) to attempt to kill members of the League (the Ultimen, barring Apache Chief expy Long Shadow, who still retained his sanity and tried to stop it).*** Rampage, a minor heroine from Franchise/{{Superman}} Post-Crisis comics, is turned into a villain in ''Unlimited''.* ''WesternAnimation/JusticeLeagueAction'': Toyman is usually a villain, but what's surprising is which one is the villain; it's Hiro Okumara, aka the HEROIC Toyman, who now instead of a hero is a villain like Winslow Shotts.* Not only, as shown in the AdaptationalVillainy/AnimatedFilm page, has Creator/{{Disney}} done this to several characters in their adoptive works, ''they've even done this to their own characters as well''. While [[ComicBook/DisneyDucksComicUniverse Scrooge McDuck]] is somewhat of a JerkWithAHeartOfGold in most of his appearances (particularly ''WesternAnimation/DuckTales'' and ''Disney/MickeysChristmasCarol''), in the ''WesternAnimation/MickeyMouseworks'' adaptation of ''Literature/AroundTheWorldInEightyDays'', he plays the main villain, determined to prevent Mickey and Goofy from gaining the inheritance necessary to save the orphanage, even going so far as to sabotage the boat taking them back to London to ensure they don't make it time.* Medusa and Comicbook/TheInhumans in ''WesternAnimation/TheFantasticFour1978''. In the comics, the Inhumans are elitist, arrogant and abrasive, but are on the side of good, and usually only fight other heroes due to {{Values Dissonance}}s or [[LetsYouAndHimFight misunderstandings]]. In the TV show, Medusa flat out wants to conquer the world and subjugate mankind, and kidnaps the Fantastic Four in order to force them to help the Inhumans accomplish this. Also, in the comics, Medusa only joined the Frightful Four because she was [[LaserGuidedAmnesia amnesiac]] at the time and was coerced by the Wizard. The cartoon has her join willingly to get revenge on the Fantastic Four. * While the Red Lantern leader Atrocitus was [[AntiHero in no way]] [[KnightTemplar a nice guy]] in the ''ComicBook/GreenLantern'' original comics, he was more of an AntiHero whose hate was focused on the Green Lantern Corps and who was reluctant to endanger innocents. His animated counterpart in ''WesternAnimation/GreenLanternTheAnimatedSeries'', while retaining his WoobieDestroyerOfWorlds backstory, is completely crazy and genocidal, willing to destroy whole planets to reach his goals and cause wars or personal tragedies to get new recruits.* Hades wasn't the only guy to fall victim to this in ''Disney/{{Hercules}}''. In the ongoing series, King Midas - of all people - was made into a would-be EvilOverlord. (Albeit [[IneffectualSympatheticVillain not a very good one]] and one who repents at the end, but still...)** Hecate is portrayed as an evil goddess who is even worse than Hades, planning to kill Hades and take over the Underworld. In mythology, Hecate was a DarkIsNotEvil goddess - besides having strong protective aspects, she assisted Demeter in finding the abducted Persephone and took pity on a slave who had foiled Hera's attempt to prevent Heracles' birth (and had been transformed into a polecat). While she lived in the Underworld, she had no intention of overthrowing Hades and became a close friend of Persephone in particular. * The incarnation of Cobra Commander in ''WesternAnimation/GIJoeResolute'' is DarkerAndEdgier and much more ruthless than the Cobra Commander in ''WesternAnimation/GIJoeSigma6'' and his other previous incarnations.* Cousin Mel in ''WesternAnimation/GrandmaGotRunOverByAReindeer''. In the original song, she only has a brief mention as playing cards with Grandpa after Grandma's death, and doesn't seem particularly malicious. In the animated special, she is the BigBad.* The animated movie ''[[Literature/{{Heidi}} Heidi's Song]]'' is a curious example of this, as it not only makes Fräulein Rottenmeier much more villainous and scary, but also turns Sebastian the butler (in the book a ServileSnarker but very much a kind man) into her [[TheDragon Dragon]] -- but utterly reverses it when it comes to Tinette the maid, who in the book is a haughty and snooty woman whom Heidi is slightly afraid of but in the movie is a sweet and sympathetic person. Possibly the shift was done so the movie wouldn't have two female villains.* ''WesternAnimation/JusticeLeagueGodsAndMonsters'':** Batman is the TokenEvilTeammate among the heroes here, being a vampire who will not hesitate to kill criminals. However, he's not Bruce Wayne in this version, but Kirk Langstrom, (as in the Man-Bat in the mainstream comic) so he can also count as AdaptationalHeroism.** Highfather is just as treacherous as Darkseid is in the mainstream universe, if not moreso.** Dear lord, '''Harley Quinn'''. clearly the most evil version of Harley to date, she's a chainsaw wielding SerialKiller who keeps the rotting corpses of her family like trophies. Even worse, the Joker is nowhere to be seen, implying she wound up like this on her own. * In an episode of ''WesternAnimation/SuperFriends'', Toyman creates a device that traps Wonder Woman inside the story of ''Literature/AliceInWonderland'', a version where the place becomes the type where EverythingIsTryingToKillYou, including the Cheshire Cat and Caterpillar, who were friendly creatures (more or less) in the actual book.* Timber Wolf's father Dr. Mar Londo gets this treatment in the ''WesternAnimation/LegionOfSuperHeroes'' animated series. While still responsible for his son's powers in the original comics (at least in Pre-Zero Hour continuity), he was in no way even suggested to be as abusive and manipulative as his animated counterpart.* While the original toyline really had no clear moral alignment to speak of, the ''WesternAnimation/{{Madballs}}'' cartoon by Creator/{{Nelvana}} had the second series Madballs (Wolf Breath, Bruise Brother, Fist Face, Splitting Headache, Swine Sucker, Lock Lips, Snake Bait, and Freaky Fullback) become a group of evil balls known as the Badballs to oppose the heroic Madballs (Screamin' Meemie, Freakella, Dusty Dustbrain, Skullface, Hornhead, Aargh, and Slobulus). It's particularly jarring because the [[ComicBook/{{Madballs}} comic book series]] by Creator/MarvelComics portrayed all the Madballs as being good.* ''WesternAnimation/MarvelUniverse'':** ''WesternAnimation/AvengersAssemble'' sees [[ComicBook/SquadronSupreme Hyperion]] gain the villainy of King Hyperion, his MirrorUniverse counterpart from ''ComicBook/{{Exiles}}''. As such, he's depicted as a sociopathic WellIntentionedExtremist who is revealed [[spoiler: to have destroyed his own planet when they wouldn't submit to his rule.]] However, given the rest of the Squardon appeared and how they behaved, it may be a downplayed version as they're more in line with the Squardon Sinister, including Nighthawk displaying the type of behavior that caused the Supreme version to leave the Squadron in disgust, though played straight with Power Princess and Nuke as the Squadron Sinister never had versions of them.** The ''WesternAnimation/GuardiansOfTheGalaxy2015'':*** Mantis as a cultist and recurring villain. This is a far cry from the comics, where Mantis is a hero and a member of the Guardians.*** Yondu is even worse version of his film counterpart, as while his film counterpart did care for Star-Lord, in the cartoon, he's got no problem throwing Quill under the bus.*** Uncle Pyko, the leader of the Halfworld Rebels. While in the original comics he wasn't completely innocent either, he was ultimately a good and peaceful man by the end, not like his portrayal here.** ''WesternAnimation/HulkAndTheAgentsOfSMASH'':*** In "Planet Leader", Hiroim (A member of the generally heroic Warbound in the comics) is the brutal slavemaster of the mines of Sakaar.*** Mainframe, an [[Comicbook/TheAvengers Avenger]] from the [[ComicBook/MarvelComics2 MC2]] line, is turned [[AIIsACrapshoot into a villain who attempts to destroy New York City]]. However, the episode does end with Mainframe leaving to experience the world after being defeated, possibly hinting that he will become a little closer to his comic counterpart.** ''WesternAnimation/{{Ultimate Spider-Man}}'' depicts ComicBook/{{Morbius}} as a willing member of ComicBook/{{HYDRA}}.* In the TV show ''WesternAnimation/MegaMan'', Proto Man is one of the major villains. In the games, while he did work for [[BigBad Dr. Wily]] [[VideoGame/MegaMan3 briefly]], he had a HeelFaceTurn and became an ally to Mega Man, if a [[AloofAlly distant one]]. * ''WesternAnimation/MummiesAlive'':** Anubis is a villain in the show, when he was actually a [[DarkIsNotEvil good god]] in Myth/EgyptianMythology who guarded and protected the dead. Set is also seen with Anubis, while Set disowned him in the myths for siding with Horus. Other gods and goddesses, like [[CatsAreMean Bastet]] and Bes, appear as villainous [[MonsterOfTheWeek Monsters of the Week]] when they were not evil figures in mythology. ** Ammit, on the other hand, is portrayed as a pet of the BigBad. In Egyptian mythology she was a neutral enforcer of order and punisher of evil, although this quality made her [[GoodIsNotNice feared by the ancient Egyptians]].* ''WesternAnimation/TheOldManOfTheMountain'': The short is based after a pre-existing song, where the Old Man isn't quite so villainous as in the cartoon.* ''Literature/{{Pinocchio}}'' is a villain the two episodes he appears in ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' where he's trying to BecomeARealBoy by ''eating the flesh of one''. (But he's AffablyEvil.) * ''WesternAnimation/MyLittlePonyFriendshipIsMagic'''s Snips' and Snails' human counterparts in ''WesternAnimation/MyLittlePonyEquestriaGirls2013'' are a lot more antagonistic than them.* Captain Hook of ''Literature/PeterPan'', while usually depicted as a LaughablyEvil and relatively mild villain (particularly in the [[Disney/PeterPan Disney adaptation]]), is genuinely sinister in ''WesternAnimation/PeterPanAndThePirates''. Despite a FreudianExcuse and occasional sympathetic moments, this version of Hook was by far the darkest portrayal of the character until the one from [[Film/PeterPan the 2003 live-action version]].* In the classic two-reel 1936 Popeye short ''WesternAnimation/PopeyeTheSailorMeetsSindbadTheSailor'', Literature/{{Sinbad}} is a villain, portrayed by Bluto. * In the original ''WesternAnimation/RainbowBrite'' Stormy is an ally of Rainbow's, even if she is grouchy. In the 2014 miniseries she is her EvilFormerFriend [[spoiler:who later undergoes a HeelFaceTurn]].* In ''WesternAnimation/TheRenAndStimpyShow'', Ren wasn't exactly the nicest guy around, but he did have [[JerkWithAHeartOfGold a softer side]][[note]]However, this was only because of ExecutiveMeddling on Creator/{{Nickelodeon}}'s part. Even then, [[DependingOnTheWriter it wasn't consistent]].[[/note]]. In ''Adult Party Cartoon'', however, his worst qualities became more prominent, his HiddenHeartOfGold was seriously played down, and he sunk to depths never explored by his older counterpart.* ''Saban's Adventures of the Little Mermaid,'' an adaptation of ''Literature/TheLittleMermaid'' fairy tale that [[FollowTheLeader draws heavily]] from [[Disney/TheLittleMermaid the Disney version]], also makes the Sea-Witch, [[NamedByTheAdaptation Hedwig]], a villain out for power. The prince's betrothed, [[NamedByTheAdaptation Cecily]], is also [[RichBitch an antagonist]], but unlike in the Disney version, they're not [[CompositeCharacter the same person]]. * In ''WesternAnimation/ScoobyDooMysteryIncorporated'', [[spoiler:Mudsy]] is a MonsterOfTheWeek and a disgruntled out-of-work actor who turned on his mystery-solving team. In his original appearances during [[WesternAnimation/TheFunkyPhantom his own show]], he was harmless and much more friendly. This is a JustifiedTrope in that it is AllJustADream and there is no "real" [[spoiler:Mudsy]] in-universe.* ''Franchise/SonicTheHedgehog'':** In the games and most cartoon adaptations, Dr. "Eggman" Robotnik is villainous, but with a highly [[AffablyEvil affable]] and [[LaughablyEvil clownish demeanor]], and in some cases leans into AntiVillain territory. Robotnik of ''WesternAnimation/SonicSatAM'' and to a lesser extent ''WesternAnimation/SonicUnderground'', however, is a monstrous (and far less humorous) dictator that not only has taken over most of the planet but thrives almost lustfully on having any remaining civilians [[BodyHorror painfully]] [[UnwillingRoboticisation roboticized]]. This depiction is drifted in and out for both comic adaptations (although they refer to his more petty, comical personality a lot more).** Inverted in ''WesternAnimation/AdventuresOfSonicTheHedgehog'' where Robotnik, while still [[CardCarryingVillain blissfully evil]], is instead portrayed as an oafish buffoon who does nothing but get kicked around by not only Sonic and Tails, but also ([[UnwantedAssistance usually inadvertently]]) by his own cronies Scratch and Grounder as well. ** In ''WesternAnimation/SonicBoom'', Shadow is a lone-wolf villain who antagonizes Sonic and friends for no real reason. In the games, while never the friendliest character, Shadow had sympathetic qualities and doubts over the morality of his actions even before his HeelFaceTurn and shows value and trust in his fellow Team Dark members.* ''Franchise/SpiderMan'':** Eddie Brock in the comics has ''some'' morals and wouldn't do half the things his ''WesternAnimation/SpiderManUnlimited'' counterpart does, including being part of an AssimilationPlot and especially working with Carnage of all people.** In the comics and most adaptations, Curt Connors is a sympathetic character and generally [[NiceGuy good-natured]] when he isn't [[SuperPoweredEvilSide the Lizard]]. In ''WesternAnimation/SpiderMan1981'', he is portrayed as a megalomaniacal monster who may have mutated himself into a humanoid reptile on purpose (he is only seen as the Lizard, but his tattered clothes and demonstration of scientific knowledge suggests that he could still be Curt Connors), while ''WesternAnimation/SpiderManTheNewAnimatedSeries'' portrays Connors as a much more bitter and unpleasant character even before his transformation.** In the comics, Eddie Brock becomes Anti-Venom, who was a [[EvilCounterpart Good Counterpart]] to the third Venom. In ''WesternAnimation/{{Ultimate Spider-Man}}'', Anti-Venom is a creation of Dr. Octopus who is an EvilCounterpart and ManOfKryptonite to Agent Venom.** Flint Marko AKA Sandman's daughter Keemia was a CheerfulChild in the comics and wasn't aware of her father's criminal activities. In ''WesternAnimation/MarvelsSpiderMan'', she is a teenager who has his powers and joins his former boss Hammerhead's side, even though she hated her dad for working for the guy. She even ''murders'' Flint in their debut episode. She is also dubbed "Sandgirl" by Spider-Man.* The ''WesternAnimation/StreetFighter'' animated series made Zangief into one of M. Bison's lackeys, despite the fact that Zangief actually opposed Shadaloo in the games.* For most of the ''WesternAnimation/SuperFriends'' series, Bizarro is depicted as a clear villain who has murderous designs on the super heroes. However, the final season depicts him faithfully from the comics as a well-meaning bumbler.* ''Franchise/TeenageMutantNinjaTurtles'':** While the [[ComicBook/TeenageMutantNinjaTurtlesMirage original comic book]] incarnation of Karai has interests that occasionally pit her against the turtles, she is unambiguously their ally. This has changed in the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003]] and [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012]] cartoon adaptations, where she has been made into the Shredder's daughter and subordinate. While she will at times fight alongside the turtles, her divided loyalties result in periods where she is wholeheartedly against them. ** The [[WesternAnimation/TeenageMutantNinjaTurtles1987 1980s cartoon]] is notable for being the only version to portray the character of Leatherhead as truly villainous, as opposed [[ComicBook/TeenageMutantNinjaTurtlesMirage to]] [[ComicBook/TeenageMutantNinjaTurtlesAdventures all]] [[WesternAnimation/TeenageMutantNinjaTurtles2003 other]] [[WesternAnimation/TeenageMutantNinjaTurtles2012 versions]] where he is an ally of the Turtles, and any time he fights them in those continuities is because of him being either NotHimself or manipulated into doing it by another antagonist.** [[spoiler:Irma in the 1987 series is April's dorky, boy crazed friend who worked with the turtles. In the 2012 series, she's actually a Kraang in a customized robotic suit who was TheMole, faking her friendship with April to find the Turtles' lair]].** In other continuities, the Rat King was a lonely man who had the ability to control rats and wanted to be left alone. In the 1987 series, he sought to take over the city for his rat friends. 2003's Rat King only attacked the Turtles when they invaded his territory. 2012's Rat King, on the other hand, started out a SmugSnake scientist [[BitchInSheepsClothing who faked concern for his colleague getting mutated]] so that he could create a serum to give him psychic powers. After becoming the Rat King, he sent his rats to attack New York and mind-controlled Splinter to attack the Turtles. Also, despite claiming to share his earlier incarnations' love for rats, [[{{Hypocrite}} he has no qualms with experimenting on them or sacrificing them in a fight]].** In ''Film/TeenageMutantNinjaTurtlesIITheSecretOfTheOoze'' and the 1987 series, Rahzar was a villain, but otherwise a very unintelligent one and cared for his partner, Tokka. The 2012 version, formerly the mutant Dog Pound (aka Chris Bradford), he's intelligent and a willing servant of the Shredder who takes pleasure at harming others and doesn't have a single concern for any of his teammates.** 2003's Mozar was a Triceraton who believed EvenEvilHasStandards, while his Mirage version existed in text only. 2012's Mozar is one of the BigBadEnsemble in season 4 of 2012's Turtles, violent and willing to destroy his minions and planets to retrieve a black hole generator.** [[ArchEnemy Shredder]] himself is an interesting case. While he was by no mean a nice guy in the Mirage comic, his sole crime was the murder of Hamato Yoshi, something he did to avenge his own brother's death, and the only reason the Turtles went after him was to avenge Yoshi's death in Splinter's name; essentially, the conflict was closer to GreyAndGrayMorality, with Shredder being the villain only because he was [[{{Jerkass}} a dick]] compared to the more noble, sympathetic Turtles. In all the adaptations, he was made somewhat more villainous to give the Turtles better reasons to go after him, typically by giving him WorldDomination ambitions. The 2k3 incarnation, aka the Utrom Shredder, didn't even have a personal connection to Yoshi outside of killing him, and was instead an alien more interested in more material ambitions until his hatred of the Turtles grew to the point that he became an OmnicidalManiac and [[WesternAnimation/TurtlesForever tried to destroy the entire multiverse just to get rid of them]]. The Nickeldeon cartoon gets closer to the comic by having him focused on revenge again, but still keeps him the villain by having him follow RevengeBeforeReason.* ''ComicBook/TeenTitans''** In the comics, Mad Mod, while initially a villain, eventually pulled a HeelFaceTurn and became a sincere supporter and ally of the new Teen Titans - he was the one who designed their costumes. In the [[WesternAnimation/TeenTitans show]], he remains an irredeemable villain throughout.** Deathstroke, while still an enemy, was less supervillain and more mercenary. He only stepped to being a major enemy of the Titans after his son's accidental death, but even then he wasn't on par with the likes of The Joker or Lex Luthor. Slade (avoiding his moniker for censorship) however is a cruel sadist and essentially a domestic terrorist who has a penchant for mass destruction and manipulation.* ''WesternAnimation/TeenTitansGo'' sees this zig-zagged and parodied with Terra. The original ''WesternAnimation/TeenTitans'' made her an example of AdaptationalHeroism. In the episode "Terra-ized", she has actions similar to her [[ComicBook/TeenTitans comic book counterpart]]; and openly tries to seduce Beast Boy in order to get sensitive information on the Titans. Only Robin and Raven suspect her of villainy, while Cyborg and Starfire are not convinced despite Terra trying to bring them down every scene she's in. When Beast Boy tries to return her advances, she drops all pretense and decides to fight the Titans for the information she needs. * In ''WesternAnimation/ThunderCats2011'', [[spoiler:Pumyra]] receives this treatment. [[spoiler:She was one of three survivors who joined the ThunderCats and was otherwise loyal to her teammates. In the 2011 series, she joined Mumm-Ra to exact revenge on Lion-O, admittedly for [[{{Hypocrite}} poor reasons]].]]** In addition, [[BigBad Mumm-Ra]] is portrayed as a much more malevolent character than he was in the [[WesternAnimation/ThunderCats1985 original series]]. In the former, his actions merely amounted to attacking the [=ThunderCats=] from time to time. But in the new series, the first thing he does is cross the MoralEventHorizon by [[spoiler:murdering Lion-O's father while disguised as Panthro.]] And he only gets MUCH worse from there. Also, in the original he had one redeeming quality in the form of [[PetTheDog his genuine love for his pet dog Ma-Mutt]]. In the new series, Ma-Mutt has been adapted out, so Mumm-Ra is pretty much irredeemable.* Tublat the gorilla from ''Literature/{{Tarzan}}'' by Creator/EdgarRiceBurroughs. In Disney's ''WesternAnimation/TheLegendOfTarzan'', his character is [[CompositeCharacter merged rather confusingly]] with another, Kerchak. Since Disney decided to make their version of Kerchak (who is ironically more similar to Burroughs's Tublat in personality) more sympathetic, as a consequence they ended up making their version of Tublat more sinister, like the novel's Kerchak.** Similarly, Professor Phineas T. Philander went from Professor Porter's absent minded friend and colleague in the books to his rival and SmugSnake in the animated series.* In the FunnyAnimal adaptation ''WesternAnimation/TheLegendsOfTreasureIsland'' Long John Silver is a more straight up LaughablyEvil villain and mostly void of the sympathetic AffablyEvil facets of his novel counterpart (and most other variations of). Perhaps most notably, his fatherly role with Jim is completely gone and for the most part, he would love nothing better than to just send the boy down the plank, or worse.* In ''Literature/TheLittlePrince'', the yellow snake, while he represents death, is not necessarily a villain, and may even be ultimately helpful. While the narrator sees him as evil, the Little Prince himself [[DontFearTheReaper does not]], [[spoiler:and it is left open as a possibility that the snake, by biting him, did help the Prince return to his asteroid]]. In the [[WesternAnimation/TheLittlePrince animated TV series adaptation]], the Snake is an unambiguously evil, even demonic EldritchAbomination who travels around the galaxy [[TheCorrupter corrupting planets]] by tempting their rulers to give in to their basest desires, while the book [[NoAntagonist didn't really have a true villain]].* ''WesternAnimation/ThomasAndFriends'':** In ''Literature/TheRailwaySeries'' novels, Diesel only returned to Sodor once in the individual story "Thomas and the Evil Diesel" where he redeemed himself and was given good word to come back. In the ''Thomas and Friends'' series, Diesel made recurring returns to Sodor and eventually became a permanent resident, though he ultimately proved as nasty as before, usually acting as the key antagonistic engine and pulling cruel pranks. Similarly to the novel version though, he is given some sympathetic moments.** Reversed for Bulgy, a bus who [[FantasticRacism disliked railways]] and tried to steal customers from the trains through lying that he accepted rail tickets. In the books, he is punished by being converted into a henhouse. While this is followed in his first appearance in the TV series, he is later repaired, changed into a vegetable stand, and [[HeelFaceTurn softens]] towards the other characters.* Brainy in ''WesternAnimation/TheSmurfs'' episode "King Smurf" became the titular character, whereas in the original comic book version he was a contender for the role of the village leader who was outvoted in favor of the Smurf who would become King Smurf. Also counts as a CompositeCharacter, since Brainy and King Smurf were not the same person in the original comic book story.* ''WesternAnimation/TheSpectacularSpiderMan'':** In the ''ComicBook/SpiderMan'' comics ComicBook/SilverSable is an [[AntiHero anti-heroic]] mercenary. While she sometimes fights Spider-Man, they usually team up to fight the real villain. In ''WesternAnimation/TheSpectacularSpiderMan'', Silver Sable is a MafiaPrincess and a straight up villain, since she's the [[DaddysLittleVillain daughter]] of the mob boss Silvermane in the show.[[note]] WordOfGod says that had the show continued, she would have [[HeelFaceTurn evolved]] into her usual anti-heroic persona.[[/note]]** Ricochet is a member of the Enforcers ([[CompositeCharacter Fancy Dan]]) rather than a teen vigilante (or originally Spidey himself) like in the comics.* ''Franchise/{{Tintin}}'': In the comic strip album ''[[Recap/TintinCigarsOfThePharaoh Cigars of the Pharaoh]]'', when Tintin drives two people to the insane asylum, the evil fakir switches the doctor's letter for a forged one that tells the personnel to lock Tintin up instead. In the Ellipse-Nelvana animated version, the doctor himself is revealed to be one of the masked villain councilmen and is implied to have written the "bad" letter himself.* ''WesternAnimation/TransformersAnimated'':** ''Animated'' actually did this to the character Waspinator from ''WesternAnimation/BeastWars''. While ''Beast Wars'' Waspinator is portrayed as the lovable ButtMonkey who does nothing but get kicked around by other characters (though he does manage to injure the occasional Maximal, usually not by accident), ''Animated'' Waspinator, now renamed Wasp, is downright terrifying, and wants to get revenge on everyone who abused him.** Sentinel Prime in the comics was one of Optimus' main allies and mentor. Here, he's a {{Jerkass}}, a [[FantasticRacism racist]], and a DirtyCoward.* While Sea Rogue from ''WesternAnimation/{{TUGS}}'' was a friend of the Star Tugs who was [[ForcedIntoEvil forced against his will to steal cargo for pirates or they'd sink his uncle]], in the CutAndPasteTranslation, ''WesternAnimation/SaltysLighthouse'', he became a villain who liked to steal cargo.* Downplayed with Cornelia from ''WesternAnimation/{{WITCH}}''. In the cartoon she's presented as more of a straight AlphaBitch than the LovableAlphaBitch she is in the comics. She's ruder and generally more aggressive. In the comics she is a BullyHunter but in the cartoon, prior to her CharacterDevelopment, she was a bully herself.* For some odd reason, ''WesternAnimation/WolverineAndTheXMen'' is FULL of this (possibly some of these characters would have returned as heroes had the second season been made):** Domino is a member of the ComicBook/XForce and ComicBook/XMen in the comics, but is depicted as a terrorist and member of the Brotherhood of Mutants in the show, basically becoming Mystique in all but name and powers as Mystique herself is TheDragon to Magneto.** Multiple Man is a member of Mr. Sinister's Marauders, despite being a main character in ''ComicBook/XFactor'' since the 90's.** Likewise, the Stepford Cuckoos are shown as villainous members of the Hellfire Club, despite being students at the Xavier Institute in the comics.** Comicbook/{{Psylocke}} assists the Brotherhood in one episode, but she's shown to be a reluctant recruit who only helps out the group because [[YouOweMe she owes Quicksilver a favor]].** Blink was associated with ComicBook/GenerationX and was a member of the ComicBook/NewMutants. Her better-known alternate version rose from ComicBook/AgeOfApocalypse mainstay to leader and main hero of the Comicbook/{{Exiles}}. In the show, she's a member of ComicBook/{{Magneto}}'s Acolytes.** Mercury, another member of the Acolytes, was a member of the [[ComicBook/NewMutants New X-Men]] in the comics.** In the comics, ComicBook/ScarletWitch and ComicBook/{{Quicksilver}} abandoned Magneto very quickly and joined Comicbook/TheAvengers. In the show, Quicksilver is still a member of the Brotherhood, while Scarlet Witch is loyal to her dad. It isn't until the finale that she finally realizes what a monster Magneto is and turns against him.** Mags himself: in the comics, he's a WellIntentionedExtremist or an AntiHero depending on the [[HeelFaceRevolvingDoor decade]]. He was last wa-ha-ha evil in TheSeventies, and the last time he was an enemy was done in such an OutOfCharacterMoment that it was {{Retcon}}ned into being someone else ''immediately'', making a ''1993'' storyline the last time we saw him as anything but his normal portrayal (half the team wants to trust him, the other half says "yeah, but you don't know '''how''' bad he was when he was bad," and his WildCard moments don't make anybody any more comfortable.) and it's not like nobody provoked him then.[[hottip:*:Of course, he gave 'em plenty of reason to think they had to strike first... it's complicated.]] WATXM Magneto appears to be similar to comic Magneto at first but at heart is as monstrous as it gets, more like his sixties/Morrison/Ultimate incarnations.** Comicbook/EmmaFrost. Like Mags, she ''used'' to be one hell of a foe (even being BigBad of ComicBook/NewMutants for a time) but comic fans know that that was a long time ago, at least in the main Franchise/MarvelUniverse. In this one she's TheMole and still the White Queen of the Hellfire Club. However, in the finale she sacrifices her life to contain the Phoenix.** ''The Phoenix.'' This is far from the first adaptation to do so, but it's worth mentioning that in the comics, Jean as Phoenix was good but AntiHero-ish, had to resist darker impulses but stayed in control (she was actually Phoenix for ''quite'' some time), and even saved the universe. It took the Hellfire Club's interference to cause her to become Dark Phoenix. This version uses TheThemeParkVersion where the Phoenix is a 100% Bad Thing. Of course, the Hellfire Club ''was'' trying to control the Phoenix in this version, but it wasn't quite the same as [[TheIllusionist Jason Wyngarde]] and [[MindControl Emma Frost]] putting her under MoreThanMindControl and pretty much breaking down her self-control bit by bit until we get a monster.* ''WesternAnimation/XMenEvolution'':** Colossus and Gambit were members of Comicbook/{{Magneto}}'s Acolytes, despite being actual members of the X-Men in the comics. They eventually pulled a HeelFaceTurn and were seen as part of the team in the epilogue. That said, Colossus is only a member of the Acolytes because Magneto is threatening his family.** ComicBook/{{Quicksilver}} and ComicBook/ScarletWitch are only in the Brotherhood in the comics because Magneto saved him and they felt they owed him, leaving upon realizing how horrible he truly was. In the show, Pietro is a bit of a sociopath and Wanda suffers from a number of mental issues.* In what could be called the villainous equivalent of the Iron Patriot in ''Film/IronMan3'', ''WesternAnimation/IvanhoeTheKingsKnight'' features the role of the Black Knight as a disguise of villains Prince John and his champion Brian de Bois-Guilbert in contrast to the novel where it was the disguise of the heroic King Richard I.* ''WesternAnimation/YoungJustice'': ** Much like the Batman example, ComicBook/KlarionTheWitchBoy is much more solidly on the side of the black hats here.** Played straight with L-Ron. In the comics, he's a sidekick to the ComicBook/JusticeLeagueInternational, while in the show he's Despero's assistant.
